However XBox plus Microsoft Gaming Studios, is still one of the biggest group of AAA publishers, they have a big enough slice of the market.
Hence why now they're dominating PlayStation charts with cross-platform games.
Many Microsoft haters don't have an good enough idea of how big they have become on games industry, regardless of layoffs and such.
SteamOS keeps being around until they feel like doing a netbooks like move, taking all their games out of Steam, or whatever else Microsoft might think of.
Hence why I regularly complain Valve should keep trying to bring developers to target GNU/Linux natively instead of translating Windows games.
